75 °C

A three neck round bottom flask was charged with 89.0 grams of the dithiophosphoric acid that was obtained from Example 9. To this was added 15.1 grams of strontium hydroxide. The reaction was heated to 75° C. for approximately 30 minutes. The reaction was attached to an aspirator to remove any water that had formed. The reaction was then allowed to cool back to 35° C., and 4.2 g of 17.5% hydrogen peroxide was added. After mixing for 2.5 hours, 11.1 grams of triethylene glycol dinonanoate was added. The reaction was then heated under vacuum and any remaining water was removed by distillation. After the temperature reached 105° C., the final product was filtered with diatomaceous earth.
